that's kinda weird, didn't the revup (exhaust side only) and HR have VVEL?

: /

VVEL is not the same as CVTC. VVEL is computer controlled intake valve lift and duration for throttle control instead of the traditional butterfly.

^ :iagree: what he said

I had this issue with mine and mostly when trying to get accelerate from dead stop making right or left turn. I agree that it is pretty scary as you would think that you can merge into traffic safely...and then the car just sits there like a lame duck.

Oh yes, warm weather definitely affects the car's performance. I wasn't able to do anything with the 'lame duck acceleration' but I added a cooler and IMO fixed 80%+ of the issue.

25 row oil cooler and issue still occurs 100% on hot days.

had no clue about that. thanks for explaining :)

before i go waste money on long pcv hoses(for a little more cooling effect),do you think that this delay is related to too much heat being dumped in the intake manifold from the pcv's ?

I would love to see someone solve this I cause cant stand it,, I have a AC and if I jam the pedal to the floor car just sits there then goes, Fun cause it feels faster off the line if I jab it like 50% till it ramps up them floor it?

im definitely going to try some experimenting with trying to keep the im as cool as possible including putting in some heat shielding from on top of the engine to block as much heat as i can.maybe its a safety measure to keep the plastic i m from melting ? if i drive normal,i dont feel this symptom.but a couple of spirited hot rodding runs takes a toll rather quick.

As "wstar" stated, throttle opening is limited at low RPM. That's the annoying feeling. I can't wait to get a new tune with updated throttle tables.

you sure that will make a difference? I have mine set at 95% open I still have a it, I actual think it has something to do with the throtlle position sensor and not the tables. For some reason it doesnt pick up you STOMPED on it for like 2 secs?

i had this problem b4, uprev solved it 90% it still not INSTANTLY but not noticeable. also the shift lag in the auto also disappeared. done at zcar garage

what i thought was related to pedal delay was in fact related to the oil that the dealer had in it when i bought it.put penzoil platinum in it tonight and what a difference it made in pick up and oil temp.

^ second that. i use PP too and definitely notice a difference after yesterday's oil change. after TP's, UPREV was the best $500 went from huge hesitation to sporty throttle response. Also re-flashed ECU (same tuned ROM) that made a difference too.

Really? That stinks. My tables are still stock other than the turbo tune. I just hate the sudden surge in 1st gear.
